PySDM v2.15

• major updates in collision methods (mostly GPU support for breakup, but also CPU refactors and cleanups & improved test coverage) - kudos @abulenok!
• numerous updates to FakeThrustRTC to support the above - kudos @abulenok
• cleanups and docstrings in Formulae-related code - kudos @abulenok

• GPU support for freezing
• 3D displacement incl. GPU support (@abulenok)

• backends: fixed __init__ calls in multiple-inheritance contexts
• FakeThrust fixes to better match ThrustRTC API (@abulenok)
• make formulae available at attribute mapper scope so request_attribute can be called without constraints
• storage, attribute, mesh common code: improved test coverage, cleanups, docstrings (@abulenok!)
• multi-stage Github Actions workflow (pylint, no-numba unit tests, etc first, only then run all the tests
• updates to make the code clean with newer versions of pylint
• new tests for displacement, freezing, breakup, mesh, builder, formulae and storage logic

PySDM v2.12

• major updates in breakup algorithmics (no more while loop, fixes) and test coverage - thanks @edejong-caltech!
• new surface-tension model tests + code fixes and cleanups - thanks @claresinger
• new product: averaged terminal velocity - thanks @sajjadazimi
• new freezing-related products: IceNucleiConcentration, FrozenParticleConcentration
• new attribute: WetToCriticalVolumeRatio
• added Fierce diagrams as a test for differences between full and linearised kappa-Koehler formulae - thanks @nriemer for hint!

PySDM v2.11

• fixing version indicators for dependencies in pypi.org-published files (regression introduced when automating package uploads)
• option to toggle overflow warning in the breakup dynamic (thanks @edejong-caltech)
• replacing r_crit<r_dry errors in wet-size equilibrium calculations with r_wet=r_dry setting (workaround for big-f_org/small-sized aerosols, thanks @claresinger)
• immersion freezing cleaups
• cleaning up imports from deprecated packages in SciPy (just subpackage naming changes)

PySDM v2.10
